- Abstract
To make use of the space and time resources at the conventional intersections using exit-lanes for left-turn (EFL) effectively, a dynamic signal-timing model for such special intersections was proposed. Firstly, the operator of the optimal period of the main signal lamp was determined by means of calculating the mean value. The concept of coordination timing of the main signal and pre-signal lights was discussed. Then the model was established with the opening and closing time of the pre-signal as the constraints, and average traffic delay as the objective function. Finally, the validity of the model was tested by taking the crossroad of Jingshi Road and Shungeng Road In Jinan City as an example. Its model was solved by the method of Enumeration with C programming. The results show that the average delay of vehicles passing through the intersection is reduced by 13.74% by dynamically adjusting the signal timing of the intersection. The timing model can make efficient utilization of the space-time resources at the intersection, thus improving the traffic capacity of the intersection.
